    I have a ezv 9.6 foot fisher plow ...I purchased the vehicle and plow used ...This is my second time using it 03/02/07 Friday . I am plowing and dragging heavy wet snow and I have noticed the right plow blade when dragging (no matter in v position or straight ) will not remain solid it releases . It only happens when I drag the plow not when pushing I can even get out and move the blade by hand in cirtain positions. Any suggestions as to what the problem might be?.

    sounds as if you may have a popit stuck open. You may want to pull the S-5 to see if you have any metal shavings or contamination.

    Take it to the dealer there is a recall on the pistons, they will put new ones in for you.

    You plows looks to be a few years old. There was a problem with some cylinders that were made in 2005 and 2006 but they would lock up and not move. That is not what you I think you have for a problem. Your crossover relief valves are in need of service, the O rings in these vales can be worn. I suggest you replace all four of these valves and adjust them as to Fisher's speck's. Use this link to Fishers mechanics guide for this power pack. http://www.fishersnowplows.com/pdf/26512_050099_web.pdf
    You will need 2 of Fisher part 7629K to be able to replace all four relief vales that control the wing drift.
